SHOCK ABSORBER.

Application filed. November 2, 1922-. Serial No. 598,550.

This invention relates to shock absorbers for automobiles.

The object of the invention is to provide a simple and eflicient device of this character which may from a car by an unskilled workman without in any way defacing the car.

Another object is to provide a shock absorber which may be used in connection w th either over or under slung springs and which operates to a great extentto holdth-e car spring in its normal positlon on ordinary roads, thereby eliminating ther-cbound of the car spring. v

With the foregoing and other obgects in view which will appear as the descrlption proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within the scope of what is claimed wlthout cleparting from the spirit of the invention.

In the accompanying draw ngs:-

Figure 1 represents a side elevation of a vehicle spring with this improved absorber shown applied, the axle of the vehicle being shown in cross section.

Fig. 2 is a front elevation of the front spring of a Ford car with this improved shock absorber shown applied.

Fig. 3 is a rear elevation of the rear spring of a Ford car with th1s improved shock absorber shown applied.

Fig. 4 is a detail elevation of one of the shackles used in connecting the absorber spring to its support, and

Fig. 5 1s a similar view of another form of shackle.

In the embodiment illustrated in Fig.1, an under slung vehicle spring S is shownof ordinary construction. in. connectlon with which the absorber 1 constituting this invention is shown applied. This absorber 1 is made in the form of a leaf spring having bearings 2 at its ends for the connection therewith of shackles 3 and 4. These shackles are exactly alike and one of them is shown in detail in Fig. 1. I These shackles each comprises two members 5 and 6 adjustably connected, the member 5 being shown connected with the spring S while the member 6 is carried by the end of spring 1. The member 5 is made substantially Y-shaped in form with a bolt 7 connecting the arms 8 be easily applied to or removed thereof and on which is mounted a roller 9 between the arms, said roller being designed to travel on the upper leaf of the spring S. The stem or shank 10 of the 1nemb-cr5 is provided. at its free. end with a plurality of longitudinally spaced apertures 11 for adjustable connection with the stem 12 of-the member 6 as is shown clearly in i. This stem 12 is made bifurcated and the furcations 13 thereof straddle the stem 10 and are connected therewith by a bolt 14. This member 6 isalso substantially Yz-shaped in form and the head 15 thereofhas itsarms 16 connected by a bolt 17, said arms being designed to straddle the bearing 2 of the absorber spring 1, while the bolt 17 extends through said bearing and thus connects the shackle member 6 with the springl In the use of this form, the spring l'constituting the absorber, is positioned below the aXleA with its ends connected by the 9 carried by said shackles being designed to travel on said spring. The spring 1 in norin Fig. 1, and this is'the position said spring would assume when relaxed, should it, be released from the shackles.

From the above description it'will be. ob-

vious that when the spring 1 is mounted as shownin Fig. 1, it will operate to hold the car spring S in its normalposition to a great extent and thus will prevent the rebound of this spring S and thereby protect the occupants of the vehicle against shocks.

It will be obvious from the above descriptionand reference to Fig. 1 that th1s absorber 1 may be readily applied to the spring shackles l) and 4 with the spring S,'therollersi S by an unskilled workman, and that its ap plication will notin any way deface the car.

In the form shown in Fig. 2,theabsorber spring 1 which is the same as that shown in Fig. 1 is connected intermediate'its ends with the front axle of the car, not shown, any suitable means being employed forthis purpose, a hanger or clamp being .here

shown.

The shackles used in connecting the absorber- 1 in the form shown in Fig; 2 differ from those used in the form shown in'Fig.

1 and the form of hanger employed in this construction is illustrated inv detail in Fig.

5. These hangers 3 and P which are connected with the respective ends of the spring 1 are designed. to be suspended from the chassis of [the :car, not shown; and 'WlllCll comprises" a U-shaped member 19 through the arms 20 and 21 of which passes a-bolt 22 on which is mounted betWeensaid arms 6 links or bars 23 and 24. This U-shaped member 19 is designed to straddle" the sup-' port on which the shackle is to be mounted, While the links 23 and'24s'traddle one end of H thecspring S as is shown clearly in Fig. 2.

i These. links" are connected at their lower endsby a-bolt'25 which also passes through th'e beari ng at one end of the spring 1 thus E nnlting the shackle until the spring locating the-spring directly below the vehicle spring.

ll. H i I the spring S 'In' the" form shown in Fig. 3, the same 19 of-the shackles are designed to be engaged With the chassis of the vehicle, thereby connecting the absorber spring 1 With the be'u'sed on other forms of vehicle than a Ford car, the embodiment herein illustrated constituting merely one application of the invention.
